Not charging I have the same product and it's a piece of ****. The only time I had to use it it didn't work as it was to be fully charged. I remarked that it discharged by itself in my glovebox. I tried to charge it, but when I plugged it into the wall and hit the charging button, it didn't worked. It's constantly beeping and no light are flashing, the charging light stays red and not flashing..... wow! an other great product from B&D!

Question moved to a Ryobi category from MISC.

If they both show charged, they are unlikely to be incorrect. You can test the contacts of the batteries with a test meter, and you can also test the charger output.

If they don't work in a tool, the tool may have failed. Having said that, they do appear to have some history of this. Check out the videos.

Hi Michelle. I have the same phone and it happened to me a few times. On most phones the battery swells up when it reaches it's charging life end. In the 9720 the battery can still LOOK okay even though it might have reached its life-span. I eventually purchased a new battery, and wholaa, problem solved. A piece of additional advice is: Do not chat with you phone on the charger. Unplug the charger when battery is fully charged: We tend to charge the phone anytime and every time before we go to work or somewhere - you have to let the battery run flat on its own at least once a month, then start a fresh charge from fully flat to fully charged. This will prolong battery life. I a new battery does not solve the problem, have the charging pin checked out. Alternately if you know someone that has the same handset as you, ask them to stick your battery into their handset and visa versa. Hope this info help :)

hello sir .. does your batteries are charged already??
if your batteries are fully charged and your camera didn`t turn on,
there`s a possibility that your camera has a problem. You can visit the store where you bought your camera and you can ask questions there why does your camera didn`t turn on whenever your batteries are ok .. :)

I'm having the same problem. Worked great then didn't last as long. Now I'm stuck with this piece of crap useless piece of equipment. I'm back to spending too much time trimming with scissors since I can't afford a new battery non the less a new trimmer. Thanks a lot WORX! It doesn't Work! I'll never buy another of their product!

with battery packs they usually die quickly that's just a con of pacs but if you didn't charge it the required amount of time the first charge you will just have to get a new pac or LOTS of batteries

The 2 flashing red lights indicate a low battery. Did you have the batteries replaced? and did you have the charger checked? The charger could not be giving you a full charge or you didn't charge the batteries correctly. It takes about 9-10 charges to bring the batteries to 100% operating capacity. Always charge the batteries before using after installing new ones and then charge nightly when you sleep. When you get up in the morning the batteries should be fully charged and last all day. Never charge more than 12 hours and always store or put up fully charged Hope this helps and sorry that no one can seem to help you except spend your money needlessly

Hello,

there i no need troubling yourself further, the problem with your phone is the charging port, the charging port of your phone is bad that is why, your phone battery cannot hold charge.

Change the charging port of your phone and your phone will charge and hold charge.

Regards.

I copied this from the Philips website... this took me FOREVER to find! Their site isn't the easiest to find products on...

"Insert the small plug into the shaver and put the powerplug in the wall socket. When you charge the appliance for the first time or after a long period of disuse, let the shaver charge for at least 16 hours. Remove the powerplug from the socket and the small plug from the shaver as soon as the batteries have been fully charged. Ignore the charge indicator when you charge the batteries for the first time. The batteries are completely new and need to be charged longer than the time indicated by the charge indicator to ensure that the back-up capacity is fully charged as well."

I hope this helps. Please remember to rate my help! I would greatly appreciate it!

Sounds like you have a bum unit.  Plantronics gives a 1 year warranty with every wireless product, I'd send it back.
Have you made sure that you're turning it on correctly?  You push the call answer button and hold it down for about 3 - 5 seconds before it turns on, until the blue light turns on.  Make sure that you don't hold it longer than that or it will go into pairing mode.
